What is the meaning of combustion?

Combustion is the process of burning of any thing in presence of oxygen.

What are the essential things for the combustion?

The essential things for the combustion are following -

1) the thing that should burn.

2) the ignition temperature of the body should be achieved.

3) supporter of the combustion.

Combustion and necessary condition

There are three major types of flame of the candle.

1) Inner zone

2) Middle zone

3) Outermost zone

Various types of zones of flame of candle

दहन का क्या अर्थ है?

ऑक्सीजन की उपस्थिति में किसी भी वस्तु के जलने की प्रक्रिया दहन है।

दहन के लिए आवश्यक चीजें क्या हैं?

दहन के लिए आवश्यक चीजें हैं -

1) वह चीज जो जलनी चाहिए।

2) शरीर के ज्वलन तापमान को प्राप्त किया जाना चाहिए l

What is the meaning of ignition temperature of combustion?

The lowest temperature which is essential for the combustion of the body, is called as the ignition temperature of the body.

There are three types of combustion -

1) Spontaneous combustion

2) Rapid combustion

3) Explosion combustion

दहन के प्रज्वलन तापमान का क्या अर्थ है?

शरीर के दहन के लिए आवश्यक न्यूनतम तापमान को शरीर का प्रज्वलन तापमान कहा जाता है।

तीन प्रकार के होते हैं दहन

१) स्वतःस्फूर्त दहन

२) तीव्र दहन

३) विस्फोट

What is the luminous zone of the flame?

It is the outermost part of the flame. In this zone, the flame occurs really. This is the region where the combustion take place at the large amount. This region of the flame is yellow in colour and this is not blue in colour.

Rapid combustion - The combustion which takes place at a high speed, and provide heat energy and light energy, that combustion is called rapid combustion.

Spontaneous combustion - Spontaneous combustion is the combustion in which the combustion takes place for small timing.

Explosion combustion - The combustion in which the combustion takes places very fastly. Such type of the combustion takes place in case of burning of crackers.

The principles of the fire extinguishers are following -

1) The combustible thing that is burning, should be removed from the place of combustion.

2) the ignition temperature of the body should be lowered.

3) supporter of the combustion should be covered by anything correctly.

The working of the fire extinguishers is to cover the area to stop fire. Carbon dioxide is used to stop burning of the things. Basically the combustible materials is covered wholly by carbon dioxide. The carbon dioxide is a gas which don't support the combustion. So, to Stop combustion, carbon dioxide is used in fire extinguisher.
